Sorry for beeing ignorant - I'm a beginner. I use Microsoft Visual C++, version 6.0. A variable of type 'long integer' can store values no more than 2.1 bln. However, I'd like to work with a substantially higher numbers, say, consisting of 30 - 40 digits (just trying to develope some primitive approach to RSA-problem). Please advise me if there any methods or programming tricks to resolve the problem. Thank you. Sincerely, Victor Goban. [email]vgoban (AT) verizon (DOT) net[/email] August 18, 2004.

There are many free C++ arithmetic libraries.
